TU has been doubling Sanders for most of the game, from what I've seen, so not throwing it to him is not surprising. BUT that should allow another receiver to get open or open up the middle for the run. Apparently not in this case.
Saw Wallace get into a heated conversation with the guy who was covering him. That might be enough to get him into the game.
Not sure what's going on with Chuba. Doesn't help that he's getting hit behind the line of scrimmage every play,. Or could be something else. He didn't seem too interested in going after that fumble in the first half.
